With some baud rates, the Arduino serial interface on my Mac receives some gibberish data and with others nothing at all. The TX led on the Arduino blinks when data is being sent btw.
Not sure how this is supposed to work without power...
...but just to test everything I tried it as well and the AtTiny stopped transmitting after pulling out the VCC cable.

No, I'm just trying to use the Arduino board as a serial interface because I don't have a separate one.
The 84's TX pin goes to the RX pin on the Arduino Uno R3 board which makes the TX led blink on the Arduino board.
I also connected a 10µF cap between RESET and GND on the Arduino
